- SASH-REGULATING, DEVICE.

Application filed January 10, 1924. Serial No. 685,329..

This invention relates to a sash regulating device-and has special reference to that class of sash raising and lowering device's -t used in automobile bodies, doors and other structures for adjustinga sash relativeto a sash frame and opening. Such devices are ordinarily located in a sash well or wall 'or door compartment with the devices operatable from the inner side of the wall or door,

' same;

and in the case of an automobile, a sash may be shifted by the driver or one of the occupants of the automobile to provide propslidable in the slot 11 of the support 8, said er ventilation.

My invention aims to provide a sash regulatmg device in which a novel arm orlever action is employed for adjusting a sash without any danger of the sash working the hard or binding in its usual guides, sash being raised and lowered perpendicular with minimum power, safety,'and assurance that the sash will remain in adjusted position. To this end, the .device includes a novel automatic clutch which precludes operation of the device of the sash and in addition to the clutch there is a simple, durable and inexpensive mechanism that may be installed.

My invention will be hereinafter specifi-' cally described and then claimed, and reference will now be had to the drawings, where- 1n Figure 1 is-a view of, the inner side ofa door frame with the side panel thereof removed to show an installation of my device;

Fig. 2 is a vertical sectional view of the Fig. 3 is an enlarged elevation of a greater part'of the device, partly in .section, showing by dot and dash lines diiferent positions which parts of the device may assume;

Fig. 4 is a plan of the device partly broken away and partly in section;

Fig. 5 is a cross sectional view taken on the line V-'V of Fig. 3;

Fig. 6 is an enlarged detail sectional view of a clutch or locking device, and

I sill 3, a well 4, sash 6, and an inside panel 7 The sash 6 normally extends into the slot of the 5111 3 and Fig. 7 is a horizontal sectional view taken on the line VII-VII of Fig. 3.,

The reference numeral 1 denotes by the way of an example, a wall or dooe frame provided with a sash opening 2, a slotted guides 5, a slidable sash because of the weight easily and quickly mally engaging is adapted to be adjusted in the guides 5 by being raised or lowered at or in the well fldenotes a transverse support that'may be set in recesses 9 of the frame '1 and suitably attached to said frame so as to extend transversely of the well .4 at approximately member being in the form of a shouldered stud which has a shoulder portion 13' in contact with walls of the slot 11 and on said stud is a spacer l4 and a washer 15.

116 denotes a longitudinally slotted arm or lever which is slidable on a stud 12 between the'spacer 14 and the Washer 15. The arm or lever 1.6 is shiftable'relative to the stud and the support 8 and may be bodily in-. verted or swung about as will hereinafter appear.

17 is a stud or bearing on one end of the arm or lever 16 and said stud or bearing is provided with a grooved roller' 18 nora rail 19 mounted on the lower or inneredge of the sash 6. Attached to the rail 19 is a stirrup 20 which retains the roller 18 in engagement with the rail 19. In some instances the rail 19 may be cut and stamped from metal to provide an in tegral stirrup and in either instance the rail and stirrup constltute an operatlve connection between the arm 16and the sash 6 so that the former may move the latter without causing any binding action of the sash in its guides 5. 1

21 denotes a shaftjournaled in thesupport 8 with one end of the shaftprovided with a large gear'whe'el' 22 and the opposite end of theshaft with a crank 23, said crank being pivotally connected, as at 24 to the opposite end of the arm 16 from the roller 18, and when the large gear wheel 22 isrotate'd the crank 23 is adapted to shift the arm 17 and cause adjustment of the sash 6, as will hereinafter appear.

25 denotes a casing suitably attached to the support 8 above the large gear wheel Journaledin the casing and the support8 is a winding arbor 27 provided with a crank 28, handle or other member which will facilitate manual rotation of the arbor 27. On the arbor 27 is a channel member 29 and loosely mounted in said channel member, over the arbor 27, is a head 30 the side walls of which may be engaged by the channel walls 31. The head 30 is provided with recesses 10 for clutch members 32, preferably in the form of small rollers and the recesses 31 have a configuration which permits of the clutch members 32 receding into the recesses to permit of the arbor 27 being rotated relative to the casing 25, otherwise, said clutch members prevent rotation of the arbor 27 especially by the large gear wheel 22 set in motion by the weight of the sash 6.

33 are springs or retaining members on the head 30 against the inner'wall of the casing and the ends of these springs are adapted to retain the clutch members 32 in distended positions, but not interfere with receding movement of said clutch members when engaged by the walls 31 of the channel member 29.

34 is a retaining washer at the. side of the head toretain the clutch members 32 on said head and at the side of said washer is a small gear wheel 35 meshing with the large gear wheel 22. The small gear wheel 4 35 is loose on the arbor 27, but is connected and then the walls of the head 30.

to the head 30 by pins 36 extending through the washer 34 into said head, said pins or like devices permitting the clutch parts to be easily assembled.

The panel 7 has an opening providin clearance for the crank or handle 28 an when said crank or handle is manually rotated, in one direction or the other, the integral channel member 29 of the arbor 27 engages certain of the clutch members 32 The engaged clutch members will release the head relative to the casing 25 and the other clutch members will follow in the direction of rotation imparted to the channel member 29. With the head 30 rotated and the small gear wheel 35 carried thereby it is obvious that the large gear wheel 22 will be rotated and cause the shaft 21 to be rocked so that the era k 33 will actuate the arm or lever 16.

Assu ing that the sash is in a raised position with the arm 16 vertical, as shown inarm 16 is gradually brought towards the horizontal and as said arm is inverted it slides on the shiftable member with said member free to ride in the horizontal portion of the slot 11 and the roller 18 free to ride against the rail 19.

From the foregoing it will be observed that the slotted arm 16 is inverted from an extreme low position ofthe sash to an extreme high position thereof, such being the opened and closed sash conditions, and it is obvious that at any intermediate position of the sash the clutch or locking device will prevent the weight oi? the sash from rotating the gearing, but not in the least interfere with manual operation of such gearing to adjust the sash. There are various kinds ofclutches or locking devices that may be associated with the gearing to prevent movement of the arm 16 due to the weight of the sash changes as are permissible by the appended claims and as may be necessary for different installations. I
